The abdominal segments and caudal rami in tthe proportional lengths 43 : 23 : 34 = 100. In the male the cephalothorax and abdomen in the proportional lengths as 60 to 40. The abdominal segments and caudal rami in the proportional lengths 37 : 23 : 40 = 100. For Boxshall & Halsey (2004, p.491) the subgenus (Dahl, 1912) is considered as full generic status pending phylogenetic revision of the whole family at the generic level.
It is probable that most of the authors having cited C. venustus Dana have referred to the form of Giesbrecht (1892) that is a synonym of C. giesbrechti.
